This is a Kosta Boda BRAINS art glass head by Bertil Vallien . It is signed on the bottom KOSTA BODA B. VALLIEN 99863 . It has silver coloring with red eyes .You can see through the top of his head into the very interesting interior of the glass . The head measures 2 7/8" long . It is in very good condition with no chips or cracks . The surface is interesting with intentional areas of distress in the silver surface giving it a unique patina .There is a worn area in the silver on the back of the head and I'm not sure if this is intentional or just wear . If you are familiar with these heads maybe you know . But overall a very interesting example .High offer pays postage .
